Leading the way with superior engineering.

Structural IntegrityThe 24-in by 162 ft-lb I-beam frame fabrication offers a lower center of gravity for less drilling vibration and increased durability, and is almost twice as heavy per foot as the DM-M2 frame (24-in by 84 ft-lb).

Operator’s ConsoleThe ergonomic PV-270 series console is designed to ensure operator comfort. The controls are logically separated into drilling and non-drilling functions, making the PV-271 and PV-275 easy to oper-ate. The drilling functions are angled to allow for easy visibility of the drill table, while large cab windows ensure that the operator has clear visibility, further enhancing the safety of the machine.

Air CompressorBoth the PV-271 and PV-275 are available with an Ingersoll-Rand low-pressure 1,900 cfm/110 psi air compressor or 2600 cfm/110 psi for rotary tricone drilling or a high-pres-sure 1,450 cfm/350 psi compressor for down-the-hole hammer drilling applications. A free 5-year/10,000 - hour compressor warranty is standard with every Ingersoll-Rand compressor.*
